Change Impact Map
A practical framework to map change dependencies and blast radius, including who/what is affected, what to test, rollout/rollback strategies, and stakeholder ownership
npx skills add majiayu000/claude-skill-registry --skill change-impact-map-amnadtaowsoam-cerebratechai-claude-2 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Change Impact Map ## Overview Documentation ที่แสดงว่า "แก้ A กระทบ B/C อะไรบ้าง" - dependency relationships ระหว่าง components ที่ช่วยให้ประเมิน impact ของ changes ได้ก่อน implement ## Why This Matters - **Risk assessment**: รู้ว่าแก้แล้วพังอะไรบ้าง - **Test coverage**: รู้ว่าต้อง test อะไรเพิ่ม - **Review scope**: รู้ว่าต้องให้ใคร review - **Rollback planning**: รู้ว่าต้อง rollback อะไรบ้าง --- ## Core Concepts ### 1. Dependency Types - **Code deps**: imports, shared modules, shared contracts, shared libraries - **Runtime deps**: services called, queues/topics, caches, feature flags, config - **Data deps**: tables/collections, schemas, indexes, migrations, analytics pipelines - **Integration deps**: third-party APIs, webhooks, auth providers, payment processors ### 2. Impact Categories - **Direct**: component ที่แก้โดยตรง (ไฟล์/โมดูล/service) - **Indirect**: สิ่งที่เรียกใช้/ถูกเรียกใช้ (upstream/downstream) - **Operational**: deploy, migrations, observability, on-call/runbooks - **User-facing**: UX, SLAs/SLOs, billing, security/compliance ### 3. Critical Paths - ระบุ P0/P1 เส้นทางที่ถ้าพังจะกระทบทั้งระบบ (auth, payments, DB connection, routing) - เชื่อมกับ SLOs และ alerts ที่มี

What does the Change Impact Map skill do?
A practical framework to map change dependencies and blast radius, including who/what is affected, what to test, rollout/rollback strategies, and stakeholder ownership
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill change-impact-map-amnadtaowsoam-cerebratechai-claude-2 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
